In a statement yesterday, Detective Chief Inspector Avine Kelly said: “We continue to work toward establishing those who possess information relating to the data breach on August 8th, and will take action to ensure that any criminality identified is dealt with robustly to keep communities, and our officers and staff who serve them, safe.”
